Jiaxing Xinsen Plastic Co., Ltd. is a HDPE Tri-color sandwich Sheet manufacturer producing multi-layer high-density polyethylene sheet from our plant in Jiaxing, Zhejiang Province. Founded in October 2001, we build three-layer co-extruded sheet in which two outer color skins bond permanently to a contrasting core, giving fabricators a visible edge line and a durable color surface that does not rely on paint or film.
Our tri-color range serves playground and amusement structures, outdoor furniture, signage, marine and industrial panels, children's products and food-contact cutting surfaces. Every order is produced to drawing or sample, so sheet size, layer colors, surface texture and thickness are set by the application rather than by a fixed catalogue.
What a Tri-Color Sandwich Sheet Is and Where It Fits
A tri-color sandwich sheet is a co-extruded HDPE panel with three distinct color layers through the thickness. Cutting, routing or thermoforming exposes the core color, so edges, engraved lettering and machined profiles stay legible without secondary painting. The construction also lets one sheet deliver two face colors plus a contrasting core for design and identification purposes.
HDPE brings balanced rigidity and toughness, resistance to acids, alkalis and corrosion, stable electrical insulation and low moisture absorption. The smooth, dense surface resists harboring bacteria, which is why the material is used for cutting boards and other frequent-contact items. Because the color runs through the sheet, wear on high-touch surfaces does not produce the chalking or flaking seen on coated panels.
- Playground and amusement equipment: colored panels, climbing walls, slide surrounds and themed cladding.
- Outdoor furniture and signage: bench slats, table tops, park signage and wayfinding boards.
- Marine and industrial: anti-corrosion panels, dock fittings, tank and pipe connection components.
- Children's products and interiors: wall-mounted toys, partition panels and flame-retardant indoor boards.
- Food-contact surfaces: kitchen cutting boards and work surfaces where a dense, non-porous face is required.
Our HDPE Sheet Range
Tri-color sheet sits within a broader HDPE family that we extrude in-house. Presenting the full range helps project teams select the right construction for each part of a build rather than forcing one sheet type across all components.

Configuration Options We Produce
Tri-color sheet is a made-to-order product. We confirm the layer structure, color combination and surface finish against the drawing before extrusion, and we can supply samples for fit and color approval.
- Layer colors: two face colors with a contrasting core, or a matched core where a subtle edge line is preferred.
- Surface finish: smooth surface, single-sided or double-sided orange-peel texture, and frosted pattern.
- Thickness and size: produced to the required sheet thickness and cut dimensions for the downstream process.
- Functional grades: UV-stabilized outdoor grades, flame-retardant indoor panels and food-contact formulations.
- Fabrication support: drawing-based processing and sample production for parts that need routing, bending or assembly.
We operate three-layer co-extrusion, orange-peel texturing, smooth surface and frosted pattern processes, which is what allows color, size and surface to be combined on one order instead of split across suppliers.

Fabrication, Installation and Line Integration
Tri-color HDPE behaves like standard HDPE on the shop floor. It can be sawn, routed, drilled, milled, bent and thermoformed with woodworking or plastic-processing equipment, and it can be welded to build larger assemblies. The color layers remain visible after machining, so engraved logos, routed grooves and edge profiles need no touch-up.
- Use sharp tooling and controlled feed rates to keep cut edges clean and color layers crisp.
- Allow for thermal expansion in long outdoor runs; HDPE moves with temperature change.
- Fasten with slotted holes or plastic-compatible fixings to avoid stress concentration.
- For welded assemblies, match the welding rod to the base HDPE grade.
Where a project combines tri-color panels with single-color structural parts, we coordinate the sheet schedule so thickness, color and finish stay consistent across the build. Related product pages such as the Marine and industrial grade HDPE Anti-Corrosion Sandwich Panel show how the material is configured for specific service conditions.
Quality Control and Acceptance
We implement full-process quality management. Inspection is carried out after each production stage, and finished sheet is checked 100% against customer requirements and international standards before packing. Our plant operates four modern, energy-saving production lines with an annual capacity of more than 20,000 tons, supported by a technical team that includes four specialists and over twenty professional technical personnel.
Acceptance for tri-color sheet normally covers layer color match against the approved sample, thickness and dimensional tolerance, surface finish and freedom from visible defects. We confirm the inspection items and sampling plan with the customer when the order is placed so that both sides work to the same criteria.

Products are exported to more than 30 countries and regions, including the United States, Brazil, Japan, Spain, Chile, Russia, Singapore, Australia and Canada.
Service, Spare Supply and Documentation
Because sheet is a consumable input rather than a machine, service means repeatable supply and consistent quality across reorders. We keep the approved color and construction on file so follow-up orders match the original delivery, and we support drawing-based processing and sample production for new parts.
- Sample production for color, texture and dimensional approval before mass production.
- Custom development from drawings or physical samples.
- Order documentation covering dimensions, grade and inspection criteria.
- Packing configured for sea freight and long-distance handling.
Frequently Asked Questions
Can you produce tri-color sheet in our own color combination?
Yes. We develop two-color and three-color sheets to order, so the face and core colors are set by your design. We recommend approving a sample before mass production to confirm the color match and edge-line contrast.
What surface finishes are available?
We produce smooth surface, single-sided and double-sided orange-peel texture, and frosted pattern. The finish can be combined with the color structure and thickness you require.
Is tri-color HDPE suitable for outdoor playgrounds?
UV-resistant HDPE is used for playground and amusement equipment, outdoor furniture and signage. The color runs through the sheet, so exposed edges and machined surfaces keep their appearance as the equipment wears.
Can the sheet be supplied flame-retardant or food-grade?
We produce flame-retardant indoor panels and food-contact formulations. Tell us the service environment and the standard you work to, and we will confirm the appropriate grade in the proposal.
How is quality verified before shipment?
Inspection takes place after each process, and finished sheet is checked 100% against customer requirements and international standards. We agree the inspection items with you at order confirmation.
What do you need to prepare a quotation?
Send the application, drawing or sample, color combination, thickness, surface finish, quantity and destination. With those inputs we can confirm the material grade, production route and delivery arrangement.
